Hi Mulyadi, thanks for the reply, > And, what kind of workload that is handled by this box anyway? Web > serving? compile farm? rendering? Is there something like "auto forking > when needed" daemon i.e dynamically forking new child when a job need to > be handled... i already solved this, sorry if I didn't post anything to tell it. The box gather some process that do video processing. I found that the issue comes with a new kernel, so i thought that was a kernel (or near kernel) issue. The problem was that the new kernel has CONFIG_HZ_1000 set, and the processes (and here's the problem) made a sleep(0) to poll the video device ( "because 'empirically' it worked" ) Of course that's wrong,even if it didn't give any problem with 100Hz. thanks, anyway. ;) bye! -- -gaspa- ----------------------------------------------- --------- Powered by Debian GNU/Linux --------- ------ HomePage: iogaspa.altervista.org ------- -Il lunedi'dell'arrampicatore: www.lunedi.org - -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
